As appears from Figs. 1 and 2 the main frame of the machine comprises a rectangular base portion 1, open at the rear, side plates 2 suitably secured to the base as'by screws 3 and zo-operating nuts fi, and a top plate 5 superposed on and xed to the side lates. A detachable front plate 6 may also e provided for covering the type bar mechanism and other parts. The main frame contains and supports the type bar system, the ribbon mechanism, the carriage feeding or escapement mechanim, parts of the tabulating mechanism and other appurtenances fu .u on to typewriting machines. The type bars are of the front strike variety, the individual type bars indicated at 'i' t; l

intacte the side plates 2 and project inward therefrom towards'each other. The type' bars 7 are arranged in guide slots 9a formed .in the segment 9 and are normally supported nea-r their free ends by an arcuate type rest 12 which lat its ends hasdepending arms 13 that are secured to the top plate 5. Each type bar is actuated by a train of devices co-operating with a slot or cam-way 14 formed in its heel portion, said train comprising a pin 15 engaging in said cam-way and projecting laterally from the upwardly extending arm 16 of a bell crank lever which comprises also a short arm 17. Said bell crank is pivoted on a pivot wire 18 common to all of the bell cranks and supported on a stationary support 19 provided with slots 20 in which the bell cranks are received. Links 21 connect the short arms 17 of the bell vcranks with key levers 22, the system of key levers being' pivoted in rear of the base on a common pivotal support 23, and each being provided at its front end with a key button or cap 24; these caps being arranged as usual on stem portions 22a that project upward at an angle from the body portions of the `key levers, thus providing a keyboard as the front of the mainframe. hile case shifting mecha# nism may be employed if desired, the character of work for which my present invention is more particularly designed, does not require'two types on a bar, a single type as shown being all that it is necessary to provide for each type bar, and hence case shifting mechanism is not needed. @n depressing the key levers their associate type bars are swung upward and rearward by the described trains of mechanism so that the types co-operate with the front face of a platen hereinafter described.

The types are adapted to print through the printing portion of a ribbon 25 that 1s wound upon spools 26, these spools .being contained in stationary cups or housings 27 arranged above the top-plate at opposite sides of the machine. The spools are adapted to be turned in alternation to feed thc ribbon back and forth by any suitable mechanism. Such ribbon feeding mechanism is not disclosed in the drawing but il have ein-l ployed in my machine the ribbon feeding mechanism of the No. l10, Remington machine,- and prefer to employ ribbon feeding mechanismof this general character. The. printing portion of the ribbon is 'threadedthrough and controlled by a vibratory ribbon carrier 28, Fig. 14, which at its upper end is 'ded in stationary grooved ways 29 bred behind the center guide 3;@ ofthe ioo type bars. The ribbon vibrator is actuated at each stroke of a printing key by a train of devices comprising a lever 31 to which the lower end of the vibrator is pivotally connected, Said lever being horizontally disposed and its pivot 32 having a stationary bearing. The forward arm of said lever 31 is pivotally connected to the upper end of a link 33, which extends downward and has its lower end pivoted to the universal bar of the machine underlying the key levers.

Mounted in the rear portion of the base is the carriage feeding or escapement mechanism which co-operates with a rack 35 on the carriage of the machine, as hereinafter more fully described. Referring especially to Figs. 1, 4, 14, 15 and 16, the carriage rack 35 has forwardly extending teeth which mesh with the teeth of a gear wheel 36 which is rigid on an axle to which one end of a main or propelling spring 37 is secured, the said axle being mounted in a stationary bracket 37a (Fig. 2) in the rear of the machine frame. This main isprin may be of any desired constructlon, such for example as that found in the Smith Premier machine. It will be understood that the tendency of the main spring 37 is constantly to urge the rack 35 and the part to which it is secured leftward across the machine. To the right of the gear wheel 36 and also meshing with the rack 35 is a feed pinion 38 secured to the upper end portion of a vertically disposed shaft 39, said shaft near its lower end having secured to it a toothed escapement wheel 40. The shaft bears in an open frame 41 which near its middle, has a rightward extension 41a that is formed ywith a hole in line with a corresponding hole in the frame 41 to bear on adjustable screw pivots 42 that project outward from a support or block 43 fixed by screws 43EL to an angle bar 43" screwed fast to the under side of the lower one of a pair of stationary guide rails 44. Said rails have more especiallyv to do with the carl-ia e to be described in detail hereinafter. set of leaf springs 45 secured by screws 46- to the support 43 co operate with-the frame 41 to maintain it normally in the position shown in Fig. 14. Adapted to co-operate with the escapement wheel 40 are escapement dogs 47 and 48 mounted on a dog rocker 49. The stepping or feed dog 47, which is normally engaged with the escapement wheel, is arranged on the top of the dog rocker 49 and comprises two parts, the dog proper 47 and a supporting part 47:1 to which the part 47 is pivoted, the part 47'?l in turn having a pivot 50 on the dog rocker, and the two-part dog being normally maintained against a stop pin 51 by a coiled spring 52. A second coiled spring 53 connects the two parts 47 and 47a and permits the part 47 to yield in a backward direction during return movements of mechanism the carriage. A stop pin 451a at the left of the stepping dog limits the extent of its stepping movement. The dog rocker 49 is fixed to the middle portion of a rock shaft 54 which bears at its ends on screw pivots secured to the sides of the base. A set screw 55 malntains a fixed relationship between the dog rocker and the rock shaft 54. Fixed to the rock shaft 54 near its ends are inclined arms 56 which are connected beneath the key levers by a universal bar or rod 57, which the key levers depress during printing operations, causing a vibration of the dog rocker and a co-action of the dogs and escapement wheel, as is usual, to permit step-by-step feeding movements of the carriage, and also actuating the'connected link 33 of the ribbon vibrating mechanism.

Tabulating devices (Figs. 1, 5 and 14), are mounted on the main frame, said devices comprising a lever arm 58 fixed to the righthand end portion of a rock shaft 59 that extends transversely of the base and bears at its ends on fixed pivotal bearings. The lever arm 58 extends upward and forward and is provided with a vertical key stem.- 60 that is capped by a tabulator key 61 isposed at the right of the keyboard. A coiled restoring spring 62 is connected to the arm 58 and to a stationary anchorage 63. Fixed to the middle portion of the rock shaft 59 is a twoply arm or stop member 64 that extends rear-V ward, said arm constituting a frame stop that co-operates with the movable tabulator stops on the carriage, as hereinafter described. Also fixed to the rock shaft at the right of the two-ply arm 64 is an upwardly extending arm 65 that is pivotally connected at 66 to an arm or rod 67 that extends rearward, passing through a thin plate-like extension or finger 68 secured to the bearing member or frame 41 by screws 69. The. rear end of the rod 67 is threaded and receives a nut that constitutes an adjustable abutment co-operating with the back of the extension 68 and connecting the tabulator with the frame 41 so that an actuation of the tabulator key 61 will swing said frame on its pivots 42, separating the pinion 38 from the rack 35 when the tabulating mechanism is operated.

Behind the main frame and its appurtenances as above described there is arranged an upright carriage structure adapted to hold the work sheet in a fiat, taut condition vertically disposed, this carriage structure being adapted to tra-vel or reciprocate for letter feeding transversely of the main frame. The bearings for the carriage structure may be of any character suitable for such reciprocation and may be supported in any suitable way. In the present instance I have shownv such bearings asfsecured to the main frame itself at the rear of-:tlie latter and while I prefer this constructidmhevertheless various other ways of constructing and mounting the bearings oi the reciprocating carriage may be employed.

As herein shown (see especially Figs. 1 and 2) the carriage supports-comprise two horimntal guide rails 44 that. are arranged one above the' other, their inner or opposing faces being grooved. These rails are immediately behind and contiguous to the rear edges of the side plates 2. 'lll-he upper rail 44. is secured near its ends by screws 71 to angular brackets 72 that. are lined to the inner faces of the side plates 2 in any suitableway, as by screws73 and co-operating nuts 74. rlfwo of these nuts co-operate with each screw 73, one nut being arranged outside the side plate 2 and the other inside and abutting against the bracket72,'the nuts exerting a clamping action. r1`he lower stationary rail 44 is secured to .the base frame 1 by screws 75. The base 1 projects slightly to the rear of the side plates 2 and the lower rail 44 rests on this projecting portionythus enabling the screws 75 to be screwed downward through the rail and into the top .0f said projecting portion which has a broad lip or ledge` The stationary rails 44 are connected through roller bearings 76 with oppositely grooved guide rails 77 that are txed to and caused to travel with the traveling carriage. The main frame of said carriage. designated as a whole by the numeral 78,- as a,t pears from Figs. 1, 2, 4 and 9, com prises two parallel vangled uprights or bars 79 which are rigidly connected by a skeletonized cross plate or bar 80. The' plate 80 comprises two triangular portions 81 connected at their apexes by an upright portion 82 which as appears hereinafter serves as a carriage stop arm. interposed between thel bases o'i the triangular portions 81 and the uprights 79 are washer plates 83. Screws 84 pass through the plates 83 into the end portions of the cross`plate and thence into the rails 77, thus securing the rails ixedly to the frame 78. Additional screws 85 passing through the parts 81 and 82 of' the cross rameinto the rails 77 assist further to secure said rails to the frame 78. rlhe feed `nach B5 with which meshes the gear wheel 36 and the escapement inion 38, is

arranged above the lower rail 7 and is secured to the cross plate 80 of the carriage by screws 85,V Mounted on the carriage frame 78 is a platen which in the present instance ll.. have shown as a rectangular metal bar' Sifrarranged transversely of the trame 78,

lbeing seated at its ends in grooves indicated at 87 formed in Ablocks 88 that are secured to the inner faces of the sidewalls of bars 79 by screws 89 and 90. The screws 89 are -o the ordinary headed sort; the screws 90 'are without heads andscrewed through the bottom ot the grooves 87 into the ends oit the bar platen 88, thus holding the platen in the miente .'xedfirelationship 'tol the carriage trame.

'letter' spaced from ,right to left, one of the type bars being shown in printing position byi dotted lines in Fig. 1. in other words the machine is 'of the class .known as front.

strike typewriting machines.

" The main carriage 78 provides a support for a secondary, carriage or paper-controllerv numeral 92. The sub-carriage 92 comprises two upright parallel bars 93 that are formed on their rear faces with rack teeth'94, these rack bars being rigidly connected at their ,upper ends by a cross piece or'bar 95, having rearwardly turned end portions 96. Ar-

rangedl between said end portions and the.

upper portions of the bars 93 are bearing plates 97 having vrearward extensions or heads 98 at their' tops. Screws 99`serve to secure the rack bars'93, plates 97 and cross bar -96 in rigid relationship. Mounted on the head portions 98 of the plates 97 are the two parts 100 and 101 of a paper clamping device. The part 100 is a cross bar which is rigidly secured at its ends to the heads 98 while the part 101 is pivotallyl mounted on said heads in rear of the xed clamping bar 100, the part 101 bearing provided with pintles 102 which bear in holes in the heads 98. The pivoted'bar 101 is cut out, as indicated at 101, so as to partly embrace the bearing portions of the heads 98 and so that the ends of said bar may be arrested by the tops of the extensions 98 which serve as limiting stops. When the clamp is operative the paper passes between the front face of the pivoted bar 101 and the rear face of the fixedlbar 100, the arran ement being such that a downward pull on t e paper will serve to wedge it tightly between the clamping bars which thus provide a positive clamp. A finger piece 103 is secured to one end of .the pivoted clamping bar by which it may be swung into and out of operative position. This nger piece is angular so that the linger portion proper extends forward within vconvenient reach of the operator as will be understood from Figs. 1 and 6. As best appears from theV last mentioned gure, spring nngers 104, secured to the bottom ot c amping bar 100, extend rearward under the bar 101, ctv-operating with the rear ,a disposed Slightly behind am lio portion thereof as detents to hdld said vbar 101 in both its operative and inoperative poj' sitions preventing looseness and rattling.

The inoperative or swung back position 1s shown by dotted lines in Fig. 6. In this position the nger piece 103 contacts with the under'face of the adjacent head 98 to prevent overthrow. A severing blade 105 is vertically arranged above the" bar 100 just forward of the clamping opening, said blade being secured to brackets 106 which are also suitably secured to the clamping bar .100. The upper sharpened ed e of the blade 105 is thus suitably positione to co-o rate with the paper after. it has passed t rou h the clamp 100, 101, so that it may rea ily be severed by bein drawn forward and downward against t e blade 105. The slidable sub-carriage, paper controller orclamp carrie`r 92, when 1n place on the main carriage, has its side bars 93 just inside the side walls of the angular bars 79 and behind the front walls of saidba'rs. The blocks 88 are cut out,

as indicated at 107 to afford a passageway for the bars 93, and provide slide bearings for the sub-carriage or clamp carrier.

Inl order to control relative movements between the secondary or sub-carriage 92 and the main carriagev 78, feeding mechanism or devices are provided comprising gear wheels' or pinions 108 which mesh with the rack teeth 94, said gear wheels being arranged on thetend portions of a shaft 109 mounted on the main carriage, the ends of the shaft being reduced as at 110 and bearing in the rearwardly extending portions of angular bearing plates 111 which are secured by headed screws 112 to the outer faces of the side walls of the carriage bars 7 9. The sub-carriage feeding devices comprising the racks 94 and gear wheels 108 are best shown in Figs. 1, 2 and 6-9. The left-hand gear wheel 108 (or,` as viewed from the rear as in Fig. 2, the right-hand gear wheel) is clamped fixedly in place on the shaft 109 by a clamping nut 113 which is threaded on the outer end portion of said shaft and clamps the wheel against a flange or enlargement 114. There is a similar clamping nut 113 and flange 114 on the opposite end of the shaft, as'illustrated more particularly in Figs. 7 and 8,l but the construction. is somewhat different, owing to the fact that the shaft-turning devices are associated with the gear wheel at the right. These shaft-turning devices comprise a ratchet wheel 115 which is secured against the shoulder 114 in any suitable way, as by soldering. The ratchet wheel is mounted on a plain portion 116 of the shaft betweenthe flange 114 and a threaded ortionv 117 on which the gear wheel 108 1s mounted. Confined between the ratchet wheel 115 and the gear wheel 108 and clamped by the nut 11-3 is a bearing ring 118 on which hears the annulus 119 of a pawl car ing arm 120 which extends rearward radial y of the shaft 109 and at its outer end ucarries a headed shoulder screw 121, which provides a bearing for an angular pawl member 122 at the lower end of which is a-tooth that is ada ted for co-operation with the teeth of t e ratchet 115, although normally separated therefrom. The pawl carrying'arm 120 has a frictional engagement with the inner face of the ratchet wheel 115 being formed withy a depression or seat 123 in which is arranged a friction spring- 124. `The coils@`vy of this spring tend constantly to expandv and thus maintain a constant friction be,-

tween the pawl carrying arm 120 and theratchet wheel 115. ln rear of its pivot 121 the pawl member 122 is pivotally connected at 125 with atwisted link 126 the present instance the V:fixing means comprise v screws 132, the rear screw screwing directly through the side wall of the bar 7 9 and the front screw through an angular bracket 133 which is screwed fast to the front wall of said bar 7 9. A spring 131a is coiled around the rock shaft 130 within the housing and hasone of its ends anchored thereto,`the other end being secured to the rock shaft, the tendencyl of said spring being constantly to raise the crank arm 128 at the rear end of said rock shaft. The rock shaft 130 extends horizontally forward and terminates in a downwardly extending handle or tin er piece 13()El which is conveniently located or manipulation by the operator, and provides both a line spacing handle and a carriage return key or handle, being adapted both to move the sub-carriage or clamp carrier upward `step-by-step on the m.ain carriage while the latter is stationary, and also thereafter, as the latter part of a single concurrent operation, to restore the main carriage and the devices mounted on it from left to right lto begin a new line of writing. To limit the movements of the pawl 122 .so as to restrict its action at each operation of turning the ratchet wheel to anL extent corresponding to a single ratchet tooth, stop devices are provided comprising an angular stop plate 134 screwed tothe upper part of the right-hand carriage bar 79 and extending rearward between the ratchet wheel 115-and the gear wheel 108, the end portion of said stopeplate 134 being so located as to co-operate-w1th the upper face of the pawl carrier 1'20 to limit the upward swing of said carrier. A Stop fingerl 135 is screwed .fast to the carriage bar 79 and extends rear ward across the path of the crank arm 128 to im downwardY movement of said crank erm and consequently 'of the pawl 122.

i @stent-devices are provided for co-operation with the line spacing mechanism to hold the sub-carriage or clamp carrier after cachot the stepfhystep u ward movements on the main carriage. aid devices coniprise a detent nose 136 that co-operates with theratchet wheel 115, said nose belng fined to a spring finger 137 screwed fast to the 'carriage har 79. Said detent is controlled by a crank arm 138 that has a rounded'fiee endcontactive with the rear 'face of the spring nger 137. As, will he understood from Figs. 6 and 7' the crank arm 138 is mounte on the inner reduced'eud of a hollow stud 139, being clamped'in place thereon by a headed screw 140 that is threaded into the bore of the stud. Mounted on the outerreduced end of said stud is a horizontall disposed and forwardly extending crank arm 1111 that is provided with a finger piece or release key 142,v said crank arm being likewise secured'to the stud 139l by a headed Vscrew 143. Said stud bears in a hollow sleeve 1411 that is fixed to the outer wall oi the right-hand angle bar 79.

In operation, an actuation of the line spacing handle 130a will rock the shaft 130, swing down the crank arm 128, pulling down on the link 126, which in turn will swing the awl member 122 on its pivot 121, causing its'tooth to engage with the ratchet wheel 115. During this swinging movement of the pawl member the carrier'120, which supports the pivot.121, will remain motionless because of its frictional connection through the spring 124 with the ratchet wheel 115. After the pawl 122 has engaged with the ratchet 1 wheel, however, further pulling movement on the link 126 will result in a turning movement of the pawl carrier 120 crank arm 128 with the stop finger 135, the

parts being so adjusted and proportioned that the movement corresponds to a line 'space distance on the work sheet. lt will A he understood that after engagement of the crank arm 128 with the stop 135, further.

power applied to the line spacing handle 130s will be transmitted to the main carriage, which up to this time has remained stationary but-which will now he returned ,towards the right on its hearings. @n releasing the line space handle or key 130 the spr 131 will become edective to ro inner face o ofthe angle'bars 79. Wire ap aerea/ie the rock shaft 130 and vthe connected train oideviees, up to and including the pawl carrier 120 and the pawl member 122, to non' mal position. During this restoring operation the ratchet wheel 115 will be held against rotationphy the detent 136, the spring 131a being strong enough to overcome the friction spr` 12d which will slide over the llnie ratchet wheel-115. Success'ive operations of the line spacing handle 75 will result in successive step-by-step upward movements of the sub-carriage on the main carriage and consequently in line space advances of the' paper or work sheet controlled by the sub-carriage. Pressure on the release key 14:2 is etlective to swing the arm 138 forward against the spring finger 137, which as it is pushed forward will throw the detent 136 out of the ratchet wheel 115, releasing thetrain of mechanism or which said ratchet wheel is a part and permitting the sub-carriage 92 to move continuously downward under the influence of the force of gravity. At this time, as will be subsequently explained more in detail, the clamp on said sub-carriage is open so that the work sheet is free from its control. The downward movement of the sub-carriage may continue until it, is arrested by engagement of the righthand part,96 with the top edge of' the stop plate 134, as shown in Fig. 6. e

lin order to control and guide the work' sheet, whether' sin leA or multiple in character, below the p aten, there areA provided devices at the lower part oi the main carriage comprising a pair of guide or presser MMD vbars which are normally spring pressed towards each other, their edect being to act as a drag on the work sheet near its lower end as it is controlled and drawn upward by clamp 1GO-101 near its upper end, with the result that the work sheet is maintained taut and dat and the usual transverse creases of long fan-fold strips or Webs are edectively smoothed or ironed out and prevented from 11o obstructing the easy upward advance of the work sheet. Referring especially to Figs. 1,

2, .5, 5a, 9 and 14, the guide or presser bars which are arranged transversely of the 'carriage are designated as 14:5 and 1116. These M5 bars are generally square in cross section but their bottom corners are rounded to facilitate entering the work sheets between them. rllhe bar 145 is seated in the angles of the right `angled bars 7 9 at their lower ends and 12o is suitably V,tired to said bars as by pins 1117 driven through them and into the ends of the bar 1215. which is thus secured to the main carriage. rllhe bar 14:6 is arranged contiguous to the rear face oi the bar 1415 and is provided at its ends'with outwardly extending pins or pintles 148 which bearin holes in the lower ends of swinging arms 1119 pivoted at 150to the inner faces of the sidewalls .-7 151 SM- 131i) cured to the outer faces of said side walls engage with said pins and tend constantly to maintain the ide bars in spring pressed engagement wlth each other. The mounting of the bar 146 affords self adjustment of it according to the character of the work' to the outer faces of the angle bars 79 and dependingjtherefrom. Mountedon said rock shaft outside said angle 'bars are camplates 154 having hubs 155 that are fitted over and suitably fixed to the rock shaft. @utside the right-hand cam plate a crank arm 156 is arranged on the rock shaft, said crank arm having a hub 157 that fits over and is fixed to the rock shaft. On the free end of said crank arm 156 is a finger piece 159 by which the rock shaft and the cam plates are .controlled. Each cam plate 154 is formed with a cam surface 154a terminating in dwells 154b and 154, the cam surface or edge and the dwells (1o-operating with the projecting pins 146. "W hen the pins 148 are opposite the dwells 154b the springs 151 are effective to maintain the pressure bars 146 and 145 in effective relationship. At this time the crank arm 1,56 is horizontally disposed, as shown in Figs.- 1 and 2. By pressing down on the finger piece 159 and swinging the crank arm 156 downward the cam faces 154a are caused to act on the pins 148, being so shaped ,as to force said pins rearward against the pressure of the springs 151, thus swinging the arms 149 rearward and carrying the bar 146 bodily rearward to the dotted line position of Fig. 5a. 1n this position said bar 146 is maintained by the co-operation of the dwells 154c with the pins 148, the bar being in effect locked so that the operator may let go the key 159 and have both hands free to manipulate the work sheet. T he latter is passed upward between the presser or guide bars 145 and 146 and to facilitate itsproper insertion, side gages or guides are provided comprising angled plates' 160- which are secured by screws 161 to the bar 146 and are of such width that they bridge the gap or space between the bars evenlwhen they are separated, said guides moving with the bar 146 across said space. After the work sheet has been inserted and passed upward over the front face of the platen and brought within the control of the clamp 100, 101 above the platen, and after the short carbon sheets are adjusted as hereinafter explained, the presser bars may be closed by swinging the linger piece 159 back toward normal position, the bars then exerting a suitable spring pressure on the work sheet throughout its width.

lt may here be noted that the tabulator stop member 64 that is mounted on the main .frame as heretofore described, is adapted to co-operate with the downwardly project' ing stop faces of column stops 162 that are adjustably mounted on a column stop bar 163 of ordinary construction, toothed on its top and bottom faces, and arranged just forward of and parallel with the presser bar 145 (see Figs. 1, 5, 5a, 9 and 14). Said columnstop bar is suitably supported on the main'carriageas by angled brackets 164 which are secured by screws 165 to the front faces of the carriage bars 79-near their lower ends. The column stop bar is secured to the under faces of the forwardly projecting horizontal portions. of said brackets by headed screws 166.

There is also mounted on the main carriage a second sub-carriage or paper controller which serves as a carbon carrier, having mounted on it detachable carbon holders which carryshort sheets of carbon paper or other suitable transfer medium that are adapted to be interleaved with a plurality of sheets of paper or the folds of a fan-fold work sheet. This carbon carrier or sub-carriage is designated as a whole by the numeral 167, being shown detached in Fig. 10. Other views which illustrate the carbon carrier and its feeding mechanism are Figs. 1, 2, 3, 4, 6, 12 and 13. rThe carbon carrier 167v comprises a cross bar 168, terminating in two cross pieces or heads 169, from eachl of which projects rearward a pair of pointed `106 pins or carrying devices 170. The cross bar 168 serves to connect two vertically disposed rack bars 171, the heads 169 being screwed fast to the. rack bars by screws 172. Each rack bar 171 is formed on its front face 105 with a series of rack teeth 173 providing racks which extend throughout the lengths of the bars. rl`he outer side faces of the bars are vformed with longitudinal grooves 174, these grooves slidably engaging with the inner edges of the front walls 'of the angle bars 79 which provide trackways for the carbon carrier. The bars'171 extend upward from the cross bar 168, and ythe bar platen 86is provided with cutouts 86a 115 to afford `passage ways for said bars 171. Limit of upward movement of the carbon carrier is determined by contact of the heads 169 with the under side of the bar platen. The carbon holders may be angular members of thin metal comprising each a horizontal bar-like body portion 175 and a short vertically disposed arm 176 integral with the body portion and extending vertically downward from one end thereof and at right angles thereto. The vertical arm 17 6`is formed with h'oles spaced apartkto fit over the associate pair of pins 170. rlhe constructionl readily enables the holders to be slipped on and off the pins, thus connecting them l with and disconnecting them from the carbon carrier. Short carbon sheets or strips 177 are attached to the bars 175 in any suitable way. For example the lower horizontal edge portion of the carbon. sheet ma be folded over and pasted to the body o the carbonv sheet, thus providing a passage way `into which the bar 175 may be passed. Each sheet extends upward from its holder, it being understood that the holders are arranged in alternation along the carbon carrying pins and in number corresponding to the work sheets or surfaces to be written on back of the first sheet, which latter is printed from the regular ribbon of the machine.

Means are provided for communicatinga slow upward feeding movement to the carbon carrier or slide frame on the main carriage frame so as to enable said sheets, although they are comparatively short to be used in writin a considerable number of bills. rllhel fee in means comprise a feed shaft 178 arrange transversely of the main carriage, said shaft bearing near its ends in bearing blocks 179 secured by screws 180 to the front faces-'of the carriage bar 79. The shaft 178 may be reduced slightly near its middle to clear the upper end of the upright bar 82 which passes .in front of it. Said shaft is formed with teeth providing ,'pinions 181 that mesh with the rack bars' `171 of the carbon carrier. These pinion portions 181 are larger in diameter than the body ofthe shaft 178 and are arranged inside the bearing blocks 179, beingadapted to contact with the inner faces thereof to prevent endwise displacement of the shaft. Fixed to the outer right-hand end portion of said shaft by a set screw 182 is an elongated hub 183 terminating in a knurled button or nger piece 184, which is operative to turn the shaft 178 and move the carbon carrier up and down at will when desired. Preferably however, the carbon carrier is fed automatically step-by-step in an, upward di-4 rection by means co-operative with the lefthand end portion of said shaft 178. Said means comprise a worm gear or wheel 185 `having a hub 186, the wo wheel being loosely mounted onvthe end portion of the shaft 178 projecting beyond ther1 'left-hand bearing block 179 by devices shown in detaill in Fig. 13. The worm wheel or 'pinion and its integral hub are lconfined between 4a flange 187 rigid with. the shaft 178 and a thimble-like part comprising a flange 188 and a hub-189,which hub fits with a ti ht frictional fit over the end of the shaft. he hub 186 of the worm gear lhas a bearing engagement with the hub 189 of the thimble. The worm gear or wheel is counter sunk, as. indicated at 190, to receive the head or flange 188 of the thimble, between which and the worm wheel is inserted a friction sprin v1.91.. The frictienA sphae four radia nciegece cuts- 192 (rig. 1a) which divide a "ica am "leayges that are so twistedas to provide fno- `tional.- resistance when the spring 1s compressed. Such compression is 'applied by a headed screw' 193 whose shank 1s threaded into the outer end of the shaft'17 8, .the head of saidscrew being adapted' to force in the.

head 188 of the thimble and compress the spring 191 more orless. amount of friction between -the gear wheel or worm wheel and the shaft 17 8 to be reguf lated with nicety since while the thimble may be moved lengthwise relatively to the shaft by 'means of the screw 193,- neverthe less said thimble fits so tightly on the shaft as to. be -in e'ect a part of it during turning movements. rlhe construction is such-that while the worm, wheel may be held positively and the shaft 17 8 may be at the same time turned by overcoming the friction due to the spring 191, yet if the worm wheel be This enables the rotated its rotative movement' will be communicated to the shaft 178 by reason of the 200 driven throughthe neck 196 and the shaft 194 serving to connect said three parts ixedly with said shaft. rThe latter bears in a sleeve or bearing block 201' having endI tabs that are secured by screws 202 to the outer face of the left-hand carriage bar 79. A. headed screw 203, threaded into the bottom en d of the shaft 194;, prevents upward displacement of said shaft. rlhe teeth of the ratchet wheel 197 are constantly engaged by the free end of a spring finger or'detent 204 secured by screws 205 to the outer face of the carriage bar V79. rll`his detent prevents the ratchet wheelv and worm gearing from turning accidentally and maintains the connected carbon carrier in adjusted positions. rlhe ratchet wheel 197 is turned to advance the carbon carrier step-by-step through a pawl member 206 provided with several teeth adapted to engagel with the ratchet teeth. The pawl member is pivoted at 207 to the under face of a horizontal plate-like end or headl2 08 of a pawl carrier which further comprises a body or bar portion 209 turned upward at right angles to the part 208 and extending rightwardly at the front side of" the carriage, terminating in an upstanding contact nose or stop 210. Near its rihthand end the pawl carrier'is formedv wit a slot 2ltwhich bears on a headed shoulder ice ric

screw 212 that is threaded into the rear upper end of the upright carriage bar or stop arm 82. This provides a slidable bearing for the right-hand end of the pawl member.

At its left-hand end the pawl member bears on the upper face of the ratchet wheel 1 97, and to this purpose the head 208 is cut out to provide a slot 213 which embraces the neck 199, the pawl member being thus loosely confined between the ratchet wheel 197 and the cap 198. A coiled spring 214, anchored at one end to the upright portion 82 and at its other end to a pin 215 on the pawl member,l tends constantly to, draw said pawl member towards the right on the carriage and to maintain' it in a normal position of arrest. Such position is determined by an adjustable screw stop 216 which is threaded into a twisted eye or lug 208a von the head 208 and is adapted normally to contact with the outer face of the carriage bar 79. A pawl spring 217 is anchored to a pin 218 extending downward from the head 208, the

other end of said spring being connected to a pin 219 on the pawl 206. The spring detent 204 is afforded a passage downward through the slot 213 for engagement with the ratchet wheel 197.

The pawl carrier 208-209 is actuated automatically during the return movements of the carriage through a margin stop 220 which projects downward into the path of the nose or stop 210, as well as into the ath of the end of the upright stop arm'82. aid margin stop 220, together with a similarly constructed carriage stop or line sto 221 is s lidably and adjustably mountedP on a toothed stop bar 222 that is arranged between the upper part of the main fra-me and the carriage, being provided near its ends with elongated slots 223 that are engaged by shouldered screws 224 threaded into the frame lugs 10. The carriage stops 220 and 221 are of any suitable construction and -are provided respectively with finger pieces 220'rl and 221a by which they may be adjusted lengthwise of their support 222 to vary the extent of carriage movement and consequently of the lines of writing. The movement of the carriage towards vthe right is determined by contact of the upper end of the arm or upright portion 82 which serves as a movable carriage stop with the margin stop 220,.while movement towards the left to end the line of writing is regulated by engagement of said stop arm 82 with the end stop 221. The end of the line is reached following the three or four step-by-step movements necessary, after engagement of the arm 82 with the stop 221, to move the stop bar v222 longitudinally leftward until the ends of slots 223 come in contact with the screws 224. The carriage having been arrested at the end of the line is restored from left to right and as it nears the end of its return movement the nose 210 will contact with the mar-l gin stop 220 and will move the stop and its vstop bar 222 towards the right until the parts are arrested by contact of the opposite or left hand ends of the slots 223 .with screws 224. After such arrest of the stop bar the further slight movement that the carriage will undergo before being finally arrested by engagement of the sto arm 8,2

with the margin stop 220 will be e ective on the pawl carrier 208, 209 to slide it left- 4ward (or as viewed from the rear rightward) in its bearings, overcoming the spring 214 and causing the pawl 206 acting on the ratchet wheel 197 to turn said ratchet wheel, thls movement being transmitted to the worm gearing 195, 185, and thence to the shaft 178 and pinions 181 which will actuate the racks 173 and move the carbon carrier 1 67 slightly upward. The extent of this movement is of course determined by the amount of turning communicated to the ratchet wheel 197 from the pawl 206, and this in turn is dependent on the position .from which the pawl starts this position be. ing regulated by the adjustment of the screw stop-216 whose inner end normally contacts with the face of the carriage bar 79. `As soon as the carriage following its return starts to move towards the left the spring 214 will become effective and through its act-ion the pawl carrier 20.8, 209 and its pawl will be restored to normal position,'as in F1g..2, with the stop 216 in cont-act with the carrlage bar 79. Repetition of the described operations will result in successive, step-bystep advance movements ofthe carbon ,carrier such movements being extremely slight due to the worm gearing, so that the carbon is fed very slowly.

Means are provided for releasingl the main from the control of the letter feeding or escapeinent mechanism, thisl being accomplished either by a hand operation or automatically when the tabulating devices arg operated. l Said means in the present instance comprises, as illust-rated in Figs. 1, 2, 9 and 14, a releasing bail composed of a cross bar 225 and crank armsh2-26 connected to the ends of the bail and pivoted at 227 to the outer faces of the carriage bars 79. The crank arms normally extend upward and forward and the bail cross bar 225 passes in front of the carriage bars 79 and transversely of the carriage, lying normally just back of and above the extension 68 on Q the swinging or rocking frame 41. The bail carriage 78 and the parts supported on it tao 79,'being pivotally connected at its upper end at 232 to the rearwardly 'extending arm of a release lever 233. The latter isfpivoted at with the extension 68, causing the upper portion of the frame 41 to swing forward about its pivots 42 and separating the feed pinion 38 from the feed rack 35, thus releasing the main carriage from the control of its letter feeding mechanism and enabling the operator to move said carriage freely towards the left by hand. This forward swing of the frame 41 does not affect the arm or link 67, which is operated by the tabulator key, the only effect being to slide the extension 68 forward along said rod or arm 67 and away from the nut or abutment 7 On releasing the key 235 therelease bail and connected devices will be restored to normal position by the spring 228, the parts being arrested by contact of the link 230 with a pin stop 236 projecting laterally from the carriage bar 79. Concurrentlythe frame 41 will be swung back by t-he'springs 4 5 causing the pinion 38 to re-engage with the rack 35. i

When the tabulator key 61-is depressed it is effective toA swing the lever arm 58 downward and the lever or stop arm 64 upward into the path of the downwardly projecting column stops 162, while concurrently the arm 65 will be swung forward, pulling the arm or link 67 and causing the nut 70, acting against the extension 68, to swing the frame forward to release the carriage. This operation of course will not affect the release bail 225, 226. As a consequence of a depression of the tabulator key, the carriage is released and will run down towards the left until arrested by the engagement of the proximate column stop with the frame stop 64. After such arrest pressure is withdrawn from the tabulator key and the parts will-be restored to normal position, the train of tabulating devices by the spring 62 and the escapement devices by the springs 45.'

In order to facilitate the insertion and adjustment of the work sheet or sheets and in cases' where it is desired to interleave carbon sheets, the machine as a'whole, comprising both the main frame and its parts and also the carriage behind the main frame,

is so mounted that it may be swung down^ ward and forward, aording access to the carriage from the front of the table. Other means of affording ready access to the carriage to facilitate the adjustment of a work sheet or sheets thereon will suggest themselves to those Askilled in art. ln the present instance, as stated, this purpose is achieved by a bodily swinging movement of When depressed said release key4 geraete the main frame and carriage together, and this operation is facilitated by mounting the carriage on a skeletonized support or stand of special construction, said stand or table being illustrated in `Figs. 1 and 1a. rl`he table or stand which is made of hollow tubing, the parts being suitably connected together, comprises two parallel horizontal bars 237 land 238, the latter being behind and somewhat lowerthan the bar 237. The bars 237 and 238 which are at the upper part of the stand are connected at their ends to the side portions thereof, said side portions each comprising a top cross bar 239 andl two depending legs 240, thefour legs being suitablybraced or connected near their lower ends, as by cross bars 240a and and rear bars 237 and 238. Secured to the sides of the main frame 1 by screws 243 are plates 244 extending downward and terminating in half-eyes 245 which engage with and are supported on the bar or rod 238. Curved pieces or complementary half-eyes 246 pass around the under side ofthe rod 238 and are detachably connected with the parts 245, as at 247 and 248. The connection 247 is a pivotal connection and the connection 248 is a detachable screw by unscrewing which the eye part 246 is released and allowed to drop downward about the pivot 247, thus affording a ready disconnection of the machine from the bar 238. lt will be understood that said eyes provide a pivotal connection of the machine4 with the frame or table, enabling the machine as a whole to be swung or rotated pivotally about the axis of the rod 238 as a center. 238a projecting upward from the rod 238 just inside the parts 245 prevent endwise displacement of the machine along the rod 238. The machine is held normally in horizontal relationship with the table by a latching device that is supported on the front bar 237, said device being in the form of a spring pin or plug comprising a cy-A Stop pins a large number of rinted blanks.

rod 237, said spring abutting against the ...inner facefof the rod at one'end and against ltion illustrated by the dottedlines in Fig.

1. The machine will be held in this dotted line position by a flexible connection or chain 255 which is anchored at 256 to the bar 237 and at its opposite end is secured to a scre`w257 that is threaded into the side of the base 1. Thus swung forward and held, the carriage is conveniently disposed to receive the work sheet or sheets.

In the present instance the work sheet illustrated is a multiple work sheet'being what is commonly known as a fan-fold sheet, and is designated as a whole' by the reference numeral' 258. rlhe fan-fold sheet 258 is of the character employed byl the ,Do-

minion Steamship Company for freight billing and comprises Six plies or folds. The first or outer ply which receives imprints directly through the ribbon 'of the machine isthe Local waybill, the second p-ly isthe Freight bill, the third ply is the Arrival notice, the fourth ply is the Delivery receipt; the fifth ply is the Prepaid freight b1ll; and the sixth ply is the Station. record. As is usual, the plies contain asuccession of printed blanks, the printed blanks on each ply being identical and the blanks bein usually some five or six inches in length. luch of the matter to be written in the. blanks on the different plies is identical, so that lall the blanks may be largely filled in at one writing on the typewriting machine. The fan-fold multiple work sheet or strip comprising the six plies or folds, more or less, is of considerable length, some fan fold strips being as lengthy, for example, as 25- feet and containing on each fold or ply For convenient handling t e six-ply strip is folded transversely at intervals of, say, eight inches, and after the leading end has been fed into the machine the folded strip may bev placed in a basket or other suitable receptacle behind the machine. With the machine swung forward and the carriage uppermost, as in the dotted-line position of Fig. 1, the operator pushes the key 159, opening the presser bars 145 and 146 so that the leading end of the fan-fold strip or sheet 258 may be conveniently passed up between them, being restricted to the properl position lengthwise of Said presser bars by the vertical contact faces of the side guides or gages 160. Thence the work sheet is drawn upward and over the front or working face of the platen 86 L and between the clamping jaws 100 and 101, the clamp having been opened by swinging the pivoted bar 101 into the dotted line position of Fig. 6.A The clamp may then be closed to grip or clamp the. upper edge por-- tion of the fan-foldsheet. Next the necessary number of carbon holders 17 5, 176 (five in the present instance'as diametrically illustrat'ed in Fig. 4) are slipped on the carrying pins 170, two holders on the left-hand set of pins and three on the right-hand set, and the short carbon sheets 177 carried by said holders are interleaved with the plies of the fan-fold sheet, as illustrated in said figure. It will .be understood that the carbon sheets 177 extend upward between the fan foldsl from their supporting bars 175 which extend between and transversely of said folds orv plies. The carbon carrier 167 having been drawn down to its lowermost position in which the ends of the cross heads 169 contact with the upper surface of the resser bar 145, the upper edge portions of t e carbon strips will be about opposite the printing line on the platen. The presser bar having` been closed by pulling forward the finger piece 159 the operator may next swing the whole machine upward on the supporting bar 238 and may lock or secure the machine 1n its normal position by causing the pin or plug 249 to engage with the eye 253`on the-- front of the machine frame. Assuming that the clamp carrier 92 has been lowered to its initial position, as illustrated in Fig. 6, and.

that in this position the blank for'the-first item that is to be duplicated on all of the lfolds is opposite the platen, then the carbe filled in. As each type bar 7 is actuated the type impression will be made on the front ply or fold of the fan-fold sheet through the ribbon 25 of the machine land y simultaneously will be duplicated on the other five plies behind the front ply through the interleaved carbon sheets. At the end of the first line of writing the line spacing handle 130a is actuated advancing the clamp carrier 92 upward on the main carriage a line space distance and drawing the multiple fan-fold strip or sheet through and between the presser bars 145 and 146, thus providing a drag which keeps the work sheet taut and smooth. At the end of the line spacing advance the crank arm 128 contacts with the stop 135 so that further pressure on the line spacing handle 130a results in a lateral vmovement of the en tire carriage structure towards' the right tovbegin4 a new line of writing. Just before the end of the line is reached the nose 210 will contact with the margin stop 220 as has been explained, resulting yin an automatic feeding movement being communicated to the carbo-n carrier 167 which will be moved slightly upward, advancing the carbon sheets between the folds of thefan-fold sheet. lt will be observed that the feeding movements of the two sub-carriages 92 and 167, while parts of a concurrent operation resulting from a single actuation of the line spacing handle, are nevertheless independent of each other; and it will also be noted that the said feeding movements vary in extent, the line spacing movement of the paper being much the greater; and these two line spacing movements are independent of the lateral movements communicated to the carriage for letter feeding, tabulating runs, and return movements to begin new lines. The operations above outlined are continued until the clamp carrier has been line spaced upward sufficiently to enable a completely written bill and its duplicates to be fed out of the machine, whereupon the clamp carrier may be retracted. Prior to retracting the clamp carrier the clamping bar 101 1s thrown back,

opening the clamp, and then the release key 142 is depressed, releasing the clamp feeding mechanism and Apermitting the clamp carrier to drop downward under the influence of gravity. Said clamp carrier may be arrestedI just below the completed bill and may then be closed, after which the completed bill and its duplicates are torn off and the plies separated for distribution in accordance with the requirement of the business. This retraction of the clamp carrier and severance of the completed multiple bill do not affect the carbon carrier, which does not reach the limit of its upward movement, owing to its slow worm feed, until a large number of bills have been completely written. and torn off.

While l have outlined above the use of the invention with one form of work sheet it will be understood that the invention may of course be employed in collating and in various styles of typewritten work. Also it is to be understood that various changes in construction may be made, and that parts of the invention may be employed without other parts, all without departing from my invention.
